It is the smaller outfits I was thinking about, particularly in the not
for profit sector.  You could offer a central backup location or you
could pair off or setup in groups similar organisations.  Schools spring
to mind they have a lot of data in digital formats and a high risk of
that data being destroyed locally, I am thinking arson and vanalism
here.  If they backed up data between each other their ability to
recover quickly from such a mishap should be hugely increased.  With 48
hours of time over a weekend even full backup of critical systems would
be possible.

Here at Shazam we have 5TB of mp3s in the music repository, we use 160GB
IDE Raid arrays to store the music and transport it about with 160GB
firewire drives.  A similar method I am sure would be practical for
emergency restores.

I am very interested in all of this and it fits well into John Hearns'
plans for GNU/Linux/BSD advocacy.  Maybe we could test out the
practicality between ADSL connections.

Peace Jim
